Abstract

UNU NTB campus activities produces inorganic and organic waste. The potential waste amount increasing provides an opportunity for managers to recyle waste into products of economic and environmental value. The purpose of this study to analyze the generation and composition of waste at UNU NTB which is the basic information for conducting integrated waste management. Field observations were made to analyze the amount of waste generated, the weight of the waste, and the percentage of waste composition. The waste generation at UNU NTB reaches 47 liters/day and the weight of waste reaches 3.74 kg/day. The composition of waste at UNU NTB consists of 77% inorganic waste and 23% organic waste. UNU NTB has 773.1 kg/year of plastic waste which generates an economic potential of IDR 2,551,190. Paper waste as much as 326.8 kg/year generates economic potential of Rp. 196,086. Organic waste is analyzed for recycling potential by recyleing organic waste into compost. The economic potential of waste is analyzed based on the price of waste at the UNU NTB Waste Bank. Organic waste at UNU NTB reaches 330.5 kg/year which has an economic potential of Rp. 1,982,880/year with reference to the market price of compost fertilizer of Rp. 6,000/kg. The potential for recycling organic waste into compost is 44 kg/year.

Abstract

Abstrak: Sampah dihasilkan dari aktivitas kampus masih belum terkelola dengan baik dan dibuang secara langsung ke TPS. Bank sampah universitas dibangun sebagai inisiatif program studi teknik lingkungan dalam upaya partisipasi menangani permasalahan sampah di Universitas Nahdlatula Ulama Nusa Tenggara Barat (UNU-NTB). Penelitian ini bertujuan untuk mengidentifikasi permasalahan dan menyusun strategi pengelolaan Bank Sampah UNU-NTB. Metode yang digunakan dalam penelitian ini adalah metode analisis SWOT secara kualitatif. Hasil penilitian menujukkan bahwa permasalahan eksisting terkait pengelolaan sampah di Bank Sampah UNU-NTB meliputi aspek sosial, aspek teknis, aspek pengelolaan, dan aspek kelembagaan. Terdapat beberapa pilihan strategi berdasarkan kajian ini yaitu memanfaatkan teknologi sebagai media untuk mengelola bank sampah, mengadakan pertemuan rutin pengelola dan nasabah, melakukan komunikasi kepada seluruh civitas akademik agar mendaftar menjadi nasabah, penyediaan sarana, dan prasarana pengelola melakukan kerjasama dengan pihak pemerintah atau swasta untuk ikut serta dalam pengembangan Bank Sampah. Abstract: Waste have been produced from campus activities is still not well managed and is gong to directly to the TPS. The waste bank universitas was built as an initiative of an environmental engineering study program as an effort to participate to reduce waste problems at Universitas Nahdlatul Ulama Nusa Tenggara Barat (UNU NTB). The purpose of The Study to identify the existing problems in waste bank and formulate a management strategy for the UNU-NTB Waste Bank. The method used in this study is a qualitative SWOT analysis method. The results of the study show that the existing problems related to waste management in the UNU-NTB Waste Bank include social aspects, technical aspects, management aspects, and institutional aspects. There are several strategic based on this study, Use technology for managing waste bank, holding regular meetings between managers and customers, communicating with the entire academic community to register as customers, providing facilities and infrastructure for managers to collaborate with government or private parties to participate in the development of the Waste Bank.

Abstract

Abstrak: Penelitian ini merupakan penelitian eksperimen dengan jenis RAK (Rancangan Acak Kelompok) yang bertujuan untuk mengetahui apakah waktu tinggal air limbah berpengaruh terhadap penurunan kekeruhan menggunakan metode pengolahan CWS-SF (Constructed wetland-Surface Flow) dengan melihat lamanya waktu tinggal air limbah pada reactor CWS berdasarkan debit aliran limbah. Metode yang digunakan adalah metode kuantitatif dimana sampel yang diuji berupa air limbah domestik pada salah satu kos-kosan dengan 12 alat uji reaktor CWS yang telah ditentukan perlakuan pada masing-masing reactor dalam menurunkan kadar kekeruhan pada air dengan melihat lamanya waktu tinggal air limbah berdasarkan debit aliran yang berbeda-beda sebagai kelompok pengulangan. Analisis data menggunakan uji ANOVA dengan aplikasi SPSS, sehingga didapati hasil penelitian bahwa terdapat data yang signifikan pada hasil uji ANOVA yaitu waktu tinggal didapatkan hasil sebesar 0,003 yang artinya lebih kecil dari nilai = 5% (0,05) maka H0 ditolak dan H1 diterima yang artinya terdapat pengaruh nyata dari lamanya waktu tinggal air limbah terhadap penurunan parameter kekeruhan limbah domestik, sedangkan pada kelompok debit aliran didapati hasil sebesar 1.000 yang artinya lebih besar dari nilai = 5% (0,05) maka H0 diterima dan H1 ditolak yang artinya tidak terdapat pengaruh nyata dari pengelompokakan debit aliran terhadap penurunan kekeruhan limbah domestk dengan sistem contructed wetlands tipe surface flow. Abstract This research is an experimental research using RAK (Randomized Block Design) which aims to determine whether the residence time of wastewater affects the reduction of turbidity using the CWS-SF (Constructed Wetland-Surface Flow) treatment method by looking at the length of residence time of wastewater in CWS reactor based on waste stream discharge. The method used is a quantitative method where the sample tested is in the form of domestic wastewater in one of the boarding houses with 12 CWS reactor test equipment that has been determined by the treatment in each reactor in reducing the turbidity level in the water by looking at the residence time of the wastewater based on discharge. different streams as repeat groups. Data analysis used the ANOVA test with the SPSS application, so the results found that there was significant data on the ANOVA test results, namely the residence time obtained a result of 0.003, which means it is smaller than the value of α = 5% (0.05) then H0 is rejected and H1 is accepted which means that there is a significant effect of the length of residence time of wastewater on the decrease in the turbidity parameter of domestic waste, while in the flow discharge group the result is 1,000, which means that it is greater than the value α = 5% (0.05) then H0 is accepted and H1 is rejected, which means there is no significant effect of the grouping of flow discharges on reducing the turbidity of domestic sewage with the surface flow type constructed wetlands system
